Artifical and assisted breeding programs l

The Gippsland Equine Hospital offers:

- Artificial Insemination

- Embryo Transfer

- Semen collection and storage

- Pregnancy testing and maintenance

The veterinarians at the Gippsland Veterinary Hospital have great expertise in animal reproduction.  Duncan Runciman has a PhD in animal reproduction and is a member of the Australian Reproductive Veterinarians Association.  The vets keep up to date with advances in the area of animal reproduction which is a fairly innovative area of veterinary medicine. 



 Artificial Insemination or AI, allows mare owners to use stallions from anywhere around the world to get the best foal possible from any given mare.  It also helps with mares that are difficult to breed for temperamental reasons or due to other disorders of the reproductive tract.

 Artificial insemination in the mare can be performed with fresh, chilled or frozen semen.  

 Fresh semen, when extended can last for several hours at room temperature.  Semen can be chilled though and last for up to four days, especially if during the initial collection and processing, steps are taken to improve the semen fertility.  We usually remove seminal plasma (the part of the semen that is not sperm), using centrifugation.  We then add semen extender that provides nourishment to the sperm to allow them to survive for several days.  

Frozen semen is kept in liquid nitrogen at minus 194 degrees!  It can be kept at this temperature for ever.  Most imported semen is frozen.

We have been providing AI services for over 10 years and have great success stories.  Our conception rates are excellent by industry standards.

Embryo transfer is the process whereby an embryo is flushed from the uterus of a mare a week after fetilisation, then transferred into another mare to maintain pregnancy.

Embryo transfer allows mare owners to keep their horse in competition while starting a breeding program.  It also allows for multiple pregnancies from each mare in a given breeding season.

Mares bred natually can be ultrasound scanned to diagnose pregnancy 13 days after ovulation.  It is a great idea to make sure your mare is not carrying twins.  We can manage twin pregnancies by reducing one of the two embryos if we scan mares before 30 days of gestation.  The process is a lot easier if we do it before day 18 of pregnancy.

Mares that have a history of abortion or poor fertility can be monitored during pregnancy to ensure the placenta and cervix are normal.  Some mares need special attention and treatment to maintain pregnancy.

We perform stallion fertility examinations.  We collect semen for insemination locally and for transport.  We also collect semen and freeze it for later use.

We teach stallions to jump on a dummy mare and use an artificial vagina for semen collection.  So far we have been able to educate every stallion we have tried.

Stallions vary a lot in their fertility.  Semen needs to be examined thoroughly.  We have most equipment required to do this in house, but may need to send semen for analysis at a specialised laboratory at time.
